NH4I will completely dissolve in ammonium and iodide ions: of which I-is neutral and NH4+ is quite a weak acid (pKa = 9.25). (The molar standard solution of NH4I will have pH approx. 4.6).
Therefore, HCl is a BrÃ¸nsted-Lowry acid (donates a proton) while the ammonia is a BrÃ¸nsted-Lowry base (accepts a proton). Also, Cl- is called the conjugate base of the acid HCl and NH4+ is called the conjugate acid of the base NH3. A BrÃ¸nsted-Lowry acid is a proton (hydrogen ion) donor. A BrÃ¸nsted-Lowry base is a proton (hydrogen ion) acceptor. In this theory, an acid is a substance that can release a proton (like in the Arrhenius theory) and a base is a substance that can accept a proton.
